A robust algorithm to find the point closest to a collection of skew lines and the line closest to a collection of skew points. This technical report presents an algorithm and code to solve for two similar classes of problems. Given a list of points, find the equations for the best line that passes a minimum distance from each point. Given a list of lines, find the point that is a minimum distance from each line. Singular value decomposition is used to solve for the inconsistant matrix.... Topic: Singular Value Decomposition
The book covers decomposition and composition of matroids. The book does not assume any prior knowledge of matroid theory. Indeed, for the reader unfamiliar with matroid theory, the book may serve as an introduction to that beautiful part of combinatorics. Topics: matroid theory, decomposition, composition
Mechanism and kinetics of hydrazine decomposition as hydrogen rich material were studied in details. Several mechanisms were studied and compared. Temperature sensitivity of reaction and probability production of different products (nitrogen, hydrogen and ammonia) according to their behaviours on catalyst surfaces were investigated. Also kinetics of hydrazine decomposition on iridium surface was maintained, analyzed and compared with common surfaces. It was investigated that different surfaces...

This paper examines the growth and instability in area, production, yield and also components of output growth of major dryland crops before (1974-1993) and after (1993-2013) the initiation of economic reforms in Andhra Pradesh. Growth rates were estimated by fitting semi-log trend equation. Cuddy Della Valle index was used to measure the instability. Contribution of area and yield towards production growth was made through decomposition. The comparison of production and acreage growth rates in...

This technical report presents an algorithm and code to solve for two similar classes of problems. Given a list of points, find the equations for the best line that passes a minimum distance from each point. Given a list of lines, find the point that is a minimum distance from each line. Singular value decomposition is used to solve for the inconsistant matrix. Numerical robustness is tested for alternate solutions to the line problem, and the best solution form is returned. This avoids... Topics: Singular Value Decomposition, Best Line Fit
Flight tests are evaluated of an avionics system which aids the pilot in making two-segment approaches for noise abatement. The implications are discussed of equipping United's fleet of Boeing 727-200 aircraft with two-segment avionics for use down to Category 2 weather operating minima. The experience is reported of incorporating two-segment approach avionics systems on two different aircraft. The cost of installing dual two-segment approach systems is estimated to be 37,015 per aircraft,... Topics: BIOGEOCHEMISTRY, CLAYS, MICROORGANISMS, MINERALS, DECOMPOSITION, ORGANIC MATERIALS
This is an example of how three phases may be formed instead of two in a phases separation mechanism. The example is the superconductor MgB2. Topics: MgB2, spinodal decomposition, three pases, phase separation
This paper decomposes changes in poverty into growth and redistribution components, and employs several pro-poor growth concepts and indices to explore the growth, poverty and inequality nexus in Indonesia over the period 2002-2012. Authors find a ‘trickle-down’ situation, which the poor have received proportionately less benefits from growth than the non-poor. All pro-poor measures suggest that economic growth in Indonesia was particularly beneficial for those located at the top of the... Topics: Growth, poverty, inequality, pro-poor, decomposition
A method and apparatus for deploying the payload of space shuttle craft or the like. The payload rotated about an axis outside of the payload but approximately longitudinally of the cargo bay of the shuttle craft. The payload may thus be rotated, through ninety degrees. In this case, that is in its rotated position, the payload may or may not have a small portion located within the cargo bay. Alternatively, the payload may be located completely outside of the bay. According to the apparatus two... Topics: CARBON, CATALYSTS, DECOMPOSITION, HYDRAZINES, HYDROGEN, PATENTS
There are currently five known groups of basaltic achondrites that represent material from distinct differentiated parent bodies. These are the howardite-eucrite-diogenite (HED) clan, mesosiderite silicates, angrites, Ibitira, and Northwest Africa (NWA) 011 . Spectroscopically all these basaltic achondrite groups have absorption bands located near 1 and 2 microns due to the presence of pyroxene. Some of these meteorite types have spectra that are quite similar, but nevertheless have... Topics: DECOMPOSITION, ALGORITHMS, POLYNOMIALS, CONSTRAINTS, GRAPHS (CHARTS)
It is observed that the stress level is function of various statistical parameters like standard deviation, entropy, energy,, mean, Co- variance and power of the ECG signals of two states i.e. normal state of mind and stressed state of mind. Further, it is observed that the features extracted are directly from the ECG in frequency domain using db4 wavelet. However, db4 introduces some error on account of db4 wavelet shape. This error in turn amplifies while measuring the features as mentioned... Topics: ECG, Bior 3.9, Wavelet \decomposition, Entropy

The Mercury Laser Altimeter (MLA) is one of the payload science instruments on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission, which launched on 3 August 2004. The altimeter will measure the round trip time-of-flight of transmitted laser pulses reflected from the surface of the planet that, in combination with the spacecraft orbit position and pointing data, gives a high-precision measurement of surface topography referenced to Mercury's center of mass....

Introducing of the weight function, which is a function of a correlation matrix determinant, permits to diminish error of spectra decomposition and to depress noise influence. The approach can be consider as an alternative of noise filtration Topics: spectra decomposition, correlation matrix, noise filtration
Presently, info concealment has become a major topic of engineering science attributable to the increasing quality of the web and also the essential want of information security. With relevancy to the final info concealment drawback, an exchange is concerned between strength, visibility and capability. There are several watermarking techniques and models and every of them has some benefits and downsides. Principally utilized in conjunction with unfold spectrum watermarking, sensory activity...

Abstract — This study quantified the hydrological responses to the forest cover change in the upper part of Sola River basin, Forest Creek catchment, southern Poland, under projected climatic conditions. The Soil Water Assessment Tool (SWAT) will be applied to investigate the response of the hydrology regime to deforestation and reforestation processes. Under two emission scenarios (A1B and B1, IPCC) of the general circulation model GISS_E (NASA Goddard Institute) were employed to generate...

In this paper, we propose a method for classification of texture images using neural network. We compared the classification result with minimum distance classifier. Most of the significant information of texture is often present in high frequency channels. So these high frequency channels are decomposed repeatedly up to fourth level to extract features like mean, energy, entropy and variance. For this 8 samples are used from brodatz album and results show that the percentage classification... Topics: Fourth Level Decomposition, Image Classification, Neural Networks

The detour distance D(u, v) between two vertices u and v in a connected graph G from u to v is defined as the length of a longest u – v path in G. The detour eccentricity eD(v) of v is the maximum detour distance from v to a vertex of G. The minimum detour eccentricity among the vertices of G is the detour radius, radD G or ( )ofG .A decomposition of a graph is a collection of edge-disjoint sub graphs , , … of such that every edge of belongs to exactly one ...
